Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an oxygen absorber packaging bag. More specifically, it relates to an oxygen absorber packaging bag used for storing foods and the like.

An oxygen absorber bag is a packaged composition that absorbs oxygen.
It has been used for the preservation of foods and the like by enclosing it in a gas barrier bag together with the foods and the like. Recently, it has been used together with an oxygen detection agent that detects the presence or absence of oxygen, and used to store foods etc. while checking whether the gas barrier bag containing foods etc. is anoxic. It became so. Since the oxygen detector changes its color depending on the presence or absence of oxygen, it is possible to confirm whether or not the food storage system is anoxic. By using this oxygen detector together with the oxygen scavenger, pinholes formed in the gas barrier bag,
It is possible to confirm an increase in the oxygen concentration in the sealed system due to a defect in the sealed seal or a decrease in the oxygen absorption capacity of the oxygen absorber.

However, since the oxygen scavenger and the oxygen detection agent have conventionally been packaged separately, when the oxygen scavenger bag and the oxygen detection agent bag are enclosed in a food packaging bag, it is difficult to work because it takes time and effort. It was Also, even in the food packaging bag,
Since the oxygen detection agent bag is small, it is difficult to find this, and it often takes time to detect the presence or absence of oxygen.

[Problems to be solved by the invention] An object of the present invention is to solve the problems of the above-mentioned conventional techniques, simplify the packaging work in a packaged food or the like using an oxygen scavenger, and It is to facilitate the confirmation of the oxygen detection agent.

[Means for Solving the Problems]

Means for solving the above problem is to form a deoxidizer packaging bag by thermally adhering a seal portion on one side of the oxygen absorber bag and one side of the oxygen detector bag.

In the above-mentioned solution means, the oxygen scavenger bag is obtained by enclosing a composition that absorbs oxygen in a breathable packaging material, and normally, for example, one sheet (paper, non-woven fabric) having at least one surface having thermal adhesiveness. , A microporous membrane, a perforated plastic film, a non-porous plastic film or a combination thereof are folded in two with the heat-adhesive surface facing inward while the oxygen scavenger is put in, and there are no folds on the three sides. Is a three-sided sealed bag or a four-sided sealed bag in which two sheets of the same or different material as described above are opposed to each other and an oxygen scavenger is placed between the two sheets to seal the four sides of the periphery. . In addition, the oxygen detection agent bag is formed by molding a composition that changes color depending on the presence or absence of oxygen, impregnated into a solid, or the like, and has at least one surface within which the color of the composition can be confirmed. Part of this is enclosed in a bag made of transparent plastic or the like, and it is usual that at least the bag is perforated at the time of use by providing a needle hole or the like.

Integration of the seal portion of the oxygen absorber bag with one side of the peripheral edge of the oxygen detector bag (the seal side is preferable when the oxygen detector bag has a seal portion) is integrated, for example, with the oxygen absorber bag and the oxygen detector. It suffices to form one of the sealing parts or one side of the bag with a heat-adhesive property, and superpose them on each other and heat-bond them from both sides with a heat roll or a heat bar.

Form a non-overlapping part on the seal part of at least one side of the oxygen absorber bag, partially expose the heat-adhesive film part,
It is particularly preferable that the oxygen detection agent bag is integrated with the peripheral edge portion, particularly the peripheral edge seal portion, by thermal bonding.

[Action]

 The oxygen absorber packaging bag of the present invention operates as follows.

Since the oxygen scavenger packaging bag of the present invention is integrated with the oxygen detector bag and the seal portion of the oxygen scavenger bag, the oxygen sensor can be put in the food wrapping bag at the same time as the oxygen scavenger bag. In addition, the food packaging bag containing the oxygen scavenger packaging bag of the present invention makes it easy to find an oxygen detection agent and easily detect an abnormal oxygen concentration in the food packaging bag.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an embodiment of the oxygen absorber packaging bag of the present invention, and FIG. 2 is a sectional view taken along line XY of FIG. Oxygen absorber
The oxygen absorber bag 10 containing 12 and the oxygen detector bag 20 containing the oxygen detector 22 are integrated. The integration of the two is that the thermal adhesive piece 50 provided on the oxygen absorber bag 10 and the oxygen detecting agent.
It is by adhesion of 20 to the seal portion 24, preferably by heat adhesion.

FIG. 3 is an enlarged view of an embodiment of an adhesive portion for integrating the oxygen absorber bag 10 and the oxygen detector bag 20. The packaging material 11 (or 111) of the oxygen absorber bag 10 is preferably made of a laminated material of at least two layers, and the inner layer 16 that forms the sealing surface.
(Or 161) is preferably made of a material having a lower softening point than the outer layer 18 (or 181). For example, inner layer 16 (or
As 161), a film made of a single film of polyethylene, polypropylene, an ethylene-vinyl acetate copolymer, an ionomer, or the like, or a composite film of the above materials, or the like is preferable. In addition, nylon is used as the outer layer 18 (or 181),
A film made of a single film of polyester such as polyethylene terephthalate, polypropylene, paper, or a composite film of the above materials is preferable. It is possible to use those provided with air permeability by providing small holes as necessary, or using at least a part made of a nonwoven fabric, a microporous membrane, or the like. An adhesive layer having a low softening point may be provided between the inner layer and the outer layer, or an adhesive material may be previously laminated on the inner layer or the outer layer. Oxygen detector bag 20
The packaging material 21 (or 211) is made of various plastic films, and at least a part of the packaging material 21 is transparent as long as the color change of the oxygen detector 22 can be confirmed.

The oxygen detection agent bag 20 is usually in the form of a bag, but in recent years, it has been found that it is formed into a sheet or printed on paper. In this case, the oxygen sensing material is not in the form of a bag,
Similar to the above, it can be integrated with the oxygen absorber bag. Therefore, the oxygen-sensing agent bag referred to in the present specification does not necessarily have to be a literal bag.

The oxygen scavenger bag 10 and the oxygen detection agent bag 20 are integrated at the seal portion by superimposing the heat-bonded piece 50 of the oxygen scavenger bag 10 and the seal portion 24 of the oxygen detection agent bag 20 on the outside, for example, a heat roll or This can be achieved by heat bonding with a heat bar or the like.
